Explanation
       2
Here -1  mean exponent 2 is only at 1 
and negative sign is without exponent. 

Let we have a polynomial

       3   2           
    = x - x + 3x + 5        

               2
Here look at -x

The exponent is only at x and negative is sign is without exponent. During solution of above polynomial we never convert it toward to positve x^2.

Similarly for further explanation 

        2           
    = 5x + 14x + 2        

                       2
Here again focus on 25x .             

The exponent is only at x and the co-efficient 7 is without exponent. During solution of above polynomial we never convert 5x^2 to 25x^2 and we can convert 25x^2 if (5x)^2 is given.

We should also understand that the order of operation (BODMAS) is the key of mathematics. and negative sign is take as multiplication so the exponent should be solve before the multiplication

Solution :
      2          2         2         
    -1  mean -(1)   and (-1) mean (-1 × -1)


      2       2
    -1  + (-1)
     
                    
    = -(1.1)  + (-1 × -1)

    = -1  + 1

    = 0
